Description of ESP8266 ESP-03 WiFi Module with Breakout

The ESP8266 WiFi Module ESP-03 Breakout is a compact and reliable Wi-Fi Serial Transceiver designed for IoT, automation, and wireless data communication projects. It integrates a powerful microcontroller with built-in Wi-Fi capability, allowing users to connect any MCU to a wireless network through a simple UART serial interface. The breakout board provides easy access to all GPIO pins of the ESP8266 (ESP-03) module, making prototyping and integration faster and more efficient.


Key Features

  • Compact Wi-Fi Serial Transceiver module based on ESP8266 ESP-03.
  • Supports TCP/IP protocol stack for Internet connectivity.
  • Built-in microcontroller with integrated Wi-Fi functionality.
  • Breakout board design for easy access to all GPIO pins.
  • Supports UART serial communication for microcontroller interfacing.

ESP8266 ESP-03 Pin Configuration

Pin Name Alternate Functions Notes
1 GND Pin 1 is in the corner close to the xtal and away from antenna
2 NC
3 UTXD SPICS1, GPIO1, CLK_RTC Typically used as serial uart0 TX
4 URXD I2SO_DATA, GPIO3, CLK_XTAL Typically used as serial uart0 RX
5 GPIO16 XPD_DCDC, RTC_GPIO0, EXT_WAKEUP, DEEPSLEEP Connected to XPD_DCDC ESP pin; can also be connected to EXT_RSTB pin to wake-up ESP from deep-sleep
6 CH_PD Power-down: low input powers down chip, high powers up; tie high for normal operation
